Title: Improvements in internal combustion turbines
IPC: F02C5/12
Filed: 1926-06-08
Abstract: 277,090. Mely, J. June 8, 1926. Axial-flow type; working-fluid supply; regulating.-An internal-combustion turbine comprises two bladed rotors 16, 19 with an intermediate ring of stator blades 18, these rotors running at different speeds and having their shafts intergeared. The gases are fed to the turbine through a channel 12 and guide vanes 13, and are generated in a series of combustion chambers 8<a> - - 8<f>. The combustion chambers work in two groups of three, the cycles in the groups being interdependent and simultaneous. Each combustion chamber has a valve 6 for admitting the mixture, a valve 9 for delivering the burnt gases and valves 7, 10 for the admission and discharge respectively of scavenging air. The valve stems carry pistons working in cylinders, and by a system of pipes 29 containing compressed air the opening of the valve 9 caused by the explosion in one chamber affects the admission of mixture to another chamber by opening the valve 6, and the scavenging of a third chamber by opening the valves 7, 10. Compressed air for the mixture is led through a pipe 2 and mixed with liquid fuel supplied by a cock 34, Fig. 1. The fuel flows through an adjustable ported sleeve 64, Fig. 7, and is discharged on to an atomizing sieve 61 in the pipe 2 forming a poor mixture with the compressed air. Additional liquid fuel is injected past a valve 35 at the moment of admission to the combustion chamber, the valve 35 being opened by a conical cam on the valve 6. When the valve 6 is restored to its seat, its stem establishes contact between members 38<1>, 89 and current is transmitted to the sparking- plugs. Speed is controlled by regulating by means of a rheostat, an electric motor driving a - rotary distributor for the current. For stopping, after the explosions have ceased, a valve 32 is opened and compressed air from the pump is admitted to nozzles 31 so as to have a braking effect on the rotor blades.

Abstract: 1474164 Hydrolysis of titanium sulphate solutions SOC ITALIANA RESINE SIR SpA 9 April 1976 [30 April 1975] 14649/76 Heading CIN Titanium sulphate solutions obtained in the sulphate process by reacting titanoferrous materials with sulphuric acid are hydrolysed by (i) gradually bringing into contact a first solution (A) of titanium sulphate having a TiO 2  titer of 230-260 g/l and an acid factor (which is the weight ratio between the sum of the free and combined sulphuric acid in the solution and the titanium content) of 1À75-1À85 heated to 88-98 C. and water at 88-98 C. to induce the formation of hydrolysis nuclei by autonucleation, (ii) gradually adding a second solution (B) of tianium sulphate having a TiO 2  titer of 230-260 g/l. and acid factor of 2À1-2À4 heated to a temperature of 88-98 C. to the mixture obtained in stage (i) maintained at 88-98 C. while maintaining a volumetric ratio A : B of 3-12 : 100 and a volumetric ratio (A + B) : water in stage (a) of 3-5 : 1 and (iii) heating the resulting mixture at boiling point to induce hydrolysis of titanium sulphate added in the stage (ii) by induced nucleation by means of the hydrolysis nuclei obtained in stage (i). The solution A may be produced from the solution B by taking a portion thereof and treating it with, e.g. ferric hydroxide, soda, caustic soda or ammonia to reduce the acid factor to 1À75-1À85. In a preferred embodiment, upon completion of the addition of solution B, the mass is brought to boiling point under stirring and maintained up to the beginning of hydrolysis when heating and stirring are stopped. Heating and stirring are recommenced again after a period of 15-45 minutes until the mass is again brought to boiling point at which it is maintained for 1-4 hours. Yield may be improved at this point by adding water in an amount of 10-20% volume at 88-98 C. and bringing the whole mass to boiling point for 1-4 hours. The hydrolysis product is conventionally treated by bleaching, addition of rutilization nuclei and mineralizing agents, milling and calcination to form TiO 2  pigments. The size of the pigment particles may be regulated by adjusting the ratio of A : B, a smaller amount of A leading to larger particles.
